Abstract:

The Quality of Service (QoS) provided for different types of multimedia applications such as audio, video, etc. The IEEE 802.16 standard defines different service classes with their associated (QoS) parameters. The MAC scheduling algorithm is the main role performing in QoS provisioning over such broadband wireless access (BWA) network and it is important that the scheduling algorithm have a multi-dimensional objective of satisfying QoS requirements of the users, maximizing system utilization and ensuring fairness among users. In this paper, we present comparative analysis for different types of MAC scheduling algorithms for the uplink (UL) connection. The proposed scheduling algorithms are compared to several other MAC scheduling algorithms for UL traffic under different mixes of traffic and for various characteristics of the IEEE 802.16 MAC layer such as throughput & delay. Simulation results indicate that MAC scheduling algorithms are not suitable for the multi-class traffic in IEEE 802.16 since they do not explicitly incorporate the QoS parameters for the given standard.
